4 operator, 12 algorithm, FM synth built with a handful of parts around the Parallax Propeller microcontroller.
The Propeller is a strangely versatile microcontroller, but it is not a DSP. Also, I do not write DSP code in real life. I don't design or build component level hardware. Nor am I even much of a musician. All these factors motivated me to take on this project.
There may also be laughably naïve techniques in my code due to all of these factors, so feedback (preferably in the form of well explained patches) are very welcome.
See circuit.txt for building details.
SPI Memory Driver.spin
is available to download from Parallax and is
provided with demo code for the Propeller Memory Card in order to talk to
the W25Q32FV.
